History of Matschie's Tree-kangaroo in North America?

[Evirapo]

This thing is getting interesting because there's no cases of Matschie's Tree-kangaroo currently held outside of NA and its native range (Beside Saint Aignan, which has single old) but how did NA got Matschie's Tree-kangaroo in the first place?

Crandall (1964) records that Sir Edward Hallstrom donated a trio of Matschie's tree-kangaroos to San Diego Zoo in 1960; he also states both of the females produced young in 1961.

Weigl (2005) records three long-lived Matschie's tree-kangaroos in North America:

(i) a female, born at the National Zoo, Washington, on 11th February 1971, died at Conservation and Research Centre, Front Royal, on 14th January 1998 at the age of 26 years 11 months.

(ii) a female, born at the Conservation and Research Centre, Front Royal, on 21st January 1980, was still alive on 27th January 2005, at the age of 25 years

(iii) a female born at the Conservation and Research Centre, Front Royal, on 6th February 1981, died at Fulsom Children's Zoo, Lincoln, 10th March 2004, the age of 23 years 1 month

That means they're inbred in NA?

That means they're inbred in NA?

Note that there are more than three founders for the population, those aren't the only ones. As for the inbred population, any population with a finite number of founders is to some degree "inbred". Granted, having, say, 300 equally represented founders is going to have a much smaller inbreeding coefficient than if there are four, unequally represented founders. Matschie's tree kangaroos aren't as inbred as some other zoo populations have been, but they also lack the luxury of having an extremely large founder base and/or the frequent influx of new founders that some others do.
